IMPROVEMENT IN REED-ORGANS.

Specification forming part of Letters Patent No. 139,874, dated June 17,1873; application filed March 29, 1873.

To all whom it may concern: y

Be it known that I, SAMUEL J. Cnocxnrr, of Boston, of the county ofSuffolk and State of Massachusetts, have invented a new and usefulImprovement in Reed-Organs; and do hereby declare the saine to be fullydescribed in the following specication and represented in theaccompanying drawings, of which- Figure 1 denotes a top view, and Fig. 2a transverse section, of part of a reed-organ with my invention. Fig. 3is an under-side view of the same. Fig. 4 is a top view of, and Fig. 5an end view of, one of the bent levers, to be hereinafter explained.Fig. 6 is a top view, and Fig. 7 a front elevation, of

`the parts with the cap-board in a vertical position.

My invention involves a reed-swell or reedinduction valve-operatingmechanism; also, a main and an auxiliary reed-valve, pivoted at theirouter ends, and connected or hinged together at their free or innerends, so as to be simultaneously operated by one key.

In the drawings, A A denote the two swell or induction valves of twoseries of reedchambers, arranged in the usual manner beneath a series ofkeys, two of which are shown at B B. From cach of the said swell-valvesa bent arm, O or O', extendsand supports at its upper part a woodencylinder, D, cushioned or covered on its upper surface with cloth. Acranked shaftv or bent lever, E or Ef, formed of wire bent in manner asshown in Figs. 4c and 5, is pivoted at its portions a a to the underside of the key-board or frame F, and arranged therewith in manner asshown. To each of the arms C O there is such a lever, the wrist b ofwhich rests directly on the cushioned cylinder of such arm. The free armc of the lever extends underneath and against the front part of anotherlever or radial arm, G, pivoted to a frame,

, H, projecting down from the cap-board I,

which usually is hinged to the organ-frame,1 so as to be capable ofbeing turned froma horizontal up into a vertical position. The radialarm Gr carries an inclined plane, d, against which another such plane,or a cam, e, iixed toa slide-rod, K, is arranged, as shown. A spring, L,applied or iixed to the hingepiece p of the arm Gr, and having its freeend resting against the arm, as shown, operates to press the arm upward.There is to each swell or induction valve A or A', and the part q towhich it is hinged, a torsion-spring, M, to effect the downward movementor closing of the swell or induction valve. Each slide-rod K is extendedthrough the nameboard f, and is provided at its front end with a knob,g.

A performer, on taking hold of the knob move the cam c against theinclined plane d, and thereby cause the radial arm G to be forceddownward. 'As a consequence, the cranked wire or lever E will be movedso as to depress the arm O, and cause it. to raise the swell orinduction valve, so as to admit air to the reed-chambers. On pushingback the slide-rod the swell or induction valve will be closed.

Each of the main reed-valves L1 is represented as having its free endhinged to the free end of an additional reed-valve, L2, arranged asshown, the connection of the two valves being eifected by a strip, h, oflinen lapped on and glued to each. The additional reed or valve, pivotedat its other end, may stand either in line with the main reed-valve orobliquely thereto, as shown in Fig. 3. From this4 it will loe seen thatboth valves may be operated or opened simultaneously by one key, or thatto the main valve.

The mechanism for operating the swell or "valve of the inducts of theseries of reedchambers is exceedingly convenient and eifective, as itbrings the knobs directly in front of the performer, and, in fact, canbe raised with the cap, so as to enable a person to readily obtainaccess to the back valve and reeds or reed-chambers.

I claim., therefore- 1. The arm G or O', the bent lever E orE,

cam c, and the slide-rod K for depressing each of the valves A or A',combined and arranged as explained, the radial arm being provided with aspring for moving it upward.

2. The slide-rod K, the inclined plane d, and the radial arm G, appliedto the cap so as to be movable therewith, as described, in combinationwith the lever E and the arm O, arranged together, and applied to thekeyframe and the valve A, as set forth.
